REPLACING A HEAD
When a head reaches 1500 build hours (odometer limit), a warning will be displayed on the User Interface and
the head’s Head Status Icon will be highlighted in red on the Materials page. You can continue using a head
which has exceeded its odometer limit, but it is highly recommended that you change the head as part quality
will be unpredictable. See “Replacing a Standard Head” on page 117 for instructions on replacing a model or
support head.
The process for replacing a PLA head varies slightly from the process for replacing a standard head. When
building with PLA material a specialized PLA head is used. The PLA head must be installed into the model head
location within the gantry. A cooling module is used in conjunction with the PLA model head and must be
installed into the support head location within the gantry. The PLA model head extrudes both model and support
materials. See “Replacing a PLA Head” on page 119 for instructions on replacing a PLA head or the associated
cooling module.
